pink taco

"Tube steak" meaning "hot dog" or "wiener" has been around as long as I
can remember, and a glance at Newspaperarchive shows many examples in
the papers, back to 1939.
I suppose it was probably originally a jocular coinage, modeled on "cube
steak".
I don't recall hearing/seeing it applied to a sex organ, but then I
haven't heard it much recently at all.
No doubt it lends itself to a sex-organ reference, just like "hot dog",
"wiener", etc., etc.
